AUTOMATIC SWIVEL-LAMP FOR AUTOMOBILES.

Specification of Letters Patent.

. Patented May 18, 1909.

Application filed December 17, 1908. Serial No. 468,028v

Toall whom it may concern:

Be it known that I, JULrUs Or'ro SPANG, of the tillage of Haileybury, in the district of Nlpissmg, in, the Province of Ontario, Canada have invented certain new and useful Improvements in .Automatlc Swivel-Lamps for Automobiles, of which the following is the specification.

My invention relates to improvements in automatic swivel lamps for automobiles, and the object of the'invention is to. devise a holder, which will provide for the automatic swinging of the lenses, so as to direct the light to "follow the course of the automobile as it passesaround curves, and thereby mini-" mi'ze the liability to accidents due to the use of the stationary form of lamps at present muse.

A further object is to make the holder and actuating means readily adaptable to various makes-of automobiles, and such as will not be liable to be effected bythe jolting of the car.

A still further object is to provide a holder of this'class in which the jar on the lamp will be reduced to a minimum.

To effect these objects my invention consists of a holder comprising a stem having a forked 11 per endin which the lamp is pivotally hel a socket for the stem attached to the frame at each sideof the automobile, an

arm attached to the stem and provided with parts bein otherwise constructed, andardetail as hereinafter more part1curanged in larly explained Figure 1, is a perspective View of the front portion of an automobile broken away to ex hibit the application of my'improved swivel lamp thereto. Fi 2, is an enlarged perspective detail of the lamp and holder therefor. Fig. 3, is an elevation of a lamp and holder partially in section. Fig. 4, is a detail of the socket connection of the supplemental arm to the connecting arm.

In the drawings like letters of reference indicate corres onding parts in each figure.

are taken by the wheels in turning. The result has been many accidents on account of the darkness in proximity to the wheels outside of the rays of the lamp as the motor is being turned, such darkness concealing in many instances curb stones and other obstructions. It is with the object of directing the light to follow .the course of the wheels and'obviate the objectionof .the stationary lamps heretofore used that my inven- A is vthe engine casing, B the side bars of the main frame, 0 the front axle and D the front. wheels. C are the vertical bearings in which are j ournaled the posts C formingpart of the brackets G which carry theshort axle E of the front wheels. 0 are forwardly extending arms from the-brackets C 0 is the arm forming portion of the brackets G which is connected toa rod C Wherebythe brackets C are turned in order to turn the wheels. F is a rod connecting the endsof the arms 0 All the parts, which I have now described are commonly in-hse in automobiles in connection with the steering of the front wheel.

G are lamps, which are ivotally hung in the forked bracket H of the holder H. H is the stem of the holder, which is provided with a shoulder H whereby it is supported upon the bearing brackets I, which areTsfe stem H is encircled by a spiral spring H underneath the bearing brackets I.

H is a washer, and H and H are nuts screwed on to the'lowerthreaded end H and designed to hold the spiral sprin in position. The s ring H serves to relievet ejolt of the vehic e upon the lamp.

J is an arm, which is provided with-a jaw J through the members of which extend the in J into the sternH thereby for-mingle. iiinged connection of the arm to the stem J 3 is a jaw formed at the opposite end of the arm J and at right angles to the plane of the face of the jaw Jf.

K is an arm 'votally swung on the pin K passing through the members of the aw J L is a rod connected at the bottom by a suitable cli L to the cross rod F. The uper end oft e rod L is provided with a socketin which fits the/ball-shaped end of the supplemental arm K. Each rod L is provided with a turn buckle M of the usual form,

whereby the length of the rod may be adjustedto different heights of frame or more properly the distance of the frame from the steerin gear.

It Wi 1 now be seen upon the steering gear.

being mani ulated so as to throw the cross rod F latera ly, that motion will be communicated from the rod F through the rod L and arms K and J to the stem H and conse quently serve to swing or swivel the lam s and direct their rays, so as to follow t'e What I- claim as my invention is:

A search light for automobiles comprising the lamp roper and a holder therefor provided witi a suitable stem vertically disposed, a socket to receive the stem secured to the frame, an arm having the inner jaw .pivotally held on the stem and an outer jaw, a rod secured to the cross bar of the turnin gear at the bottom'end and provided with a ball socket at the up er end, and a supplemental arm havin a all fitting 'in the aforesaid socket and the opposite end pivotally held within the. outer jaw of the aforesaid arm as and for the purpose s ecified.
